BAND-TYING GAUGE.

Application mea my 2, 1924.' senin no. rea-sca e This invention relatesto improvements in gauges for use intying driving ban'ds of band drivenmachines7 with a regulated tension, the improved device being especiallyadapted for use in tying the spindle driving bands of spinning ortwisting frames.

-The invention has for its object to provide a simple and durable deviceof the character set forth so constructed as'to decrease the labor andtime required'in tying bands.

In the drawings Fig. k1 is a side elevation of the device attached to aspindle rail ready for use;l v

The device comprises an att-achmentand positioning member 1 which isslotted at its llower, end and provided withlugs 2 yat the on 'the lineopposite vert-ical sides of the slot. Between 40v these lugs the lowerend'of a swinging tenf the slot so that there can be no free `upand`r inthe member 1 and are secured inV position b the aivot 'ain 4.` The liwslsnugly fit y l l e;

downimovement of the bracketI 5 independently of the member l. Two majorparts 7 and 8 comprise'r thebracket. The part .7' has the lugs 6 formedthereon,'and this part projects outwardly a short distance from Fig. 3 alvertical sectional view of the de`l the memberl. The projectingportion.. of

the part is formed in halves kthat are sep? karable on a horizontal`plane and are adapted to be held togetherv by vaj central screw' 9.

The part 8 of the bracket is in the formof afloop that is adapted toengage theflowerV end ofa spindle bearing or bolster 10, whichdependsfrom the rail `11 of the spinning frame. This-loopissubstantially U-shaped,l

preferably made cfg-wire and is formed at l itsendswith .shortdownturnedfportions 12. H i

Thel ends of the loop are adaptedto. be clamped in grooves formed inthejabuttfing, faces ot the separable halves ofthe part? oi.r thebracket, and the downturned ends' 12 "zoL are receivedinlverticalVopenings 13 inthe lower half. Owing lto this structure the loop l8 maybe readily removed by simplyfun-Vv screwing the screw 9 and removing thelower Ahalfoit the part 7.r Provision'is thus made for readily removingone'loop and substitut` :pf

The Vpurpose o't'these guiding 'andY Yrgefiiifiia tying hookduring the operation of pulling the ends of the band in order to placethel proper tension on the band. In Fig. 11 the operation of theseretaining and` guiding rollers is illustrated. Spindle driving' bandsare usually formed of two strandstwisted together. A loop is'formed atone end and at the other endthe two strands are separated. One of theseseparated ends is passed thiough the said loop 1in one direction and theother is passed through the loop in the opposite direction when it isdesired to tie the band to the spindle'. `As shown in Fig. 11, theseparated strands, after they have been passed through the loop in theend of the band7 are passed outwardly in opposite directions under theguiding and retaining l rollers 50. The inturned portions i8 of the I y15 forces it forwardly, that is to say, toward ferent conditions.

'plate 47 above the rollers extend rearwardlyy ofthe rollers to formguards and are flared upwardly to facilitate' the entrance of theYstrands to the rollers( These guards combine with the rollers 50 to formin effect guiding andretaining hooks. It isinanifest Vt-hat these hooksServe to hold the band down casting. The said plate yis readilyYremovable from the casting in case of ybreakage vof either part and theplate may be replaced by another plate of different proportions Vorhaving diiferentlyspaced rollers to `suit dif- The tying hook 34. whichprojects upwardly from the free end of the arm 33 of the tension memberis formed' from one end of a strand. of thick wire 51 that is cast inthe tension ymember 3 and extends longi- .tudinally through the centerof the arm'33 and downwardly through theinainportion the tension memberto a point adjacent the spring passage 18.' The castingis greatlystrengthened by this wire and the hook 34; is securely anchored rlieoperation of tying the band is as follows: "j

The lower 'endof the spindle bearing 10 is engaged in the loop-8 of thebracket 5, and th-e member 1 is then swung upwardly to bring its innerface into engagement with the spindle krail 11 and to cause the springljaws 28"L to engage the whorl 27 withinthe groove therein. The notclior`recess 25 of Ythe bracket 21 receives the spindle bearing andthe-bracket bears against the lower face Vof the whorl. All Aof theseparts .serve'to center the member 11 properly 'a'nd'vto' hold it Thetension inem- `the operator, a-nd downwardly to the limit of itsmovement.` The lug '13.serves as a V.limit stop. The spindle drivingbandf'is then passed around the drive pulley or cylinder andv onopposite sides ofthe spindle whorl and its ends brought togetherin frontof the tying lug 34. One strand of the band I is passed through thelendloop ofthe band in one direction andVv the otlierqstrand ispassedtlirough said loop inthe vopposite direction. The separatedstrands are then passed laterally in opposite direetions'under the-retaininghooks formed by the guards 48 and theiiollers50( The operatori then pullsV outwardly von the said strands. This causes the strands tobear strongly against the. rollers.l It willbeunderstood that as thestrain is vput on the separated strands they are pulledv out orunrayeled from the main body fof the band.' This sliortens t-he bandandputs a strain onthev rollers of the retaining hooks andy draws :thetension member upwardlyfand toward the spindle.V lt sometimes occursthatthelooped end of the band will remain'between thefre taining hooksduring .the tying `operation and will not engage'tlie'tyingl hool. 1nthis.
